Toy top

ABSTRACT

A toy top includes three components. A first component has a hole. A second component has an insertion unit which can be inserted in the hole to a first depth position, and the second component can be turned manually. A third component is prevented from moving in a depth direction in the hole when attached to the first component. A groove is provided with a guide section which makes the protrusion slide against an inner surface of a groove wall on one side to make the insertion unit rise to a second depth position and which prevents the insertion unit from falling out. The third component has a part which functions as a stopper that prevents the insertion unit from moving to a first depth position direction.

BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates to a toy top.

Description of Related Art

Traditionally, there is known a toy top which includes a configurationwhere an upper layer member having a function to attack the opponent'stoy top, a middle layer member having a function to determine the heightof the toy top and a lower layer member having a function to determinethe moving manner of the toy top are layered (for example, see JapaneseUtility Model No. 3151700).

With respect to such toy top, a plurality of types of upper layermember, middle layer member and lower layer member are provided and atoy top is formed by assembling one upper layer member, one middle layermember and one lower layer member each of which is selected from theplurality of types thereof. Here, a screw is used to connect the upperlayer member and the middle layer member.

However, especially in a toy top used for a battle game, the followingproblems exist in a case where a screw type connecting member(component) is used.

That is, the connecting member might become loose or come off when animpact force is applied in the direction that makes the connectingmember become loose when the toy tops collide with each other in a toytop battle. Specifically, in the case where the connecting member isused at the center section of the body of the toy top and if an impactforce is applied to the body, a large force is applied to the connectingmember and it is easily loosened. When the connecting member becomesloose, the toy top loses its original attacking function. Further, whenthe connection member falls out, the connecting member and othercomponents will fly away.

Here, although the connecting member which connects the upper layermember and the middle layer member is described above, the same problemsalso exist in the case where the components other than the connectingmember are assembled by using screw type connecting members.

Although it isnot limitative in any way, the upper end of the cylindrical pillar 16 isset to be higher than the upper end of the cylinder 13. At the upper endsection of the cylindrical pillar 16, two hooks (the second hooks) 17that protrude toward outside in the diameter direction are respectivelyformed at the positions that face each other in the front-rear directionhaving the axis of the spinning shaft 11 therebetween.

The shaft unit 10 further includes a cylindrical pressing member 18.Although the pressing member 18 is made of synthetic resin here, it canbe made of metal. The pressing member 18 is provided inside the cylinder13 so as to surround the outer circumference of the cylindrical pillar16.

As shown in FIG. 5, the pressing member 18 includes a cylinder unit 18a, a ceiling 18 b and legs 18 c.

The ceiling 18 b is provided at the upper end of the cylinder unit 18 a.The ceiling 18 b includes a hole 18 d formed in the shape thatcorresponds to the upper end part of the cylindrical pillar 16.

Further, the legs 18 c are formed at the lower end part on the outerperiphery of the cylinder unit 18 a. Two legs 18 c are respectivelyformed at the positions that face each other in the front-rear directionhaving the axis of the spinning shaft 11 therebetween. Each of the legs18 c is formed of a horizontal unit 180 c which protrudes horizontallyfrom the cylinder unit 18 a and a vertical unit 181 c which extendsdownward in the vertical direction from the tip of the horizontal unit180 c.

The pressing member 18 having the above configuration is provided sothat the legs 18 c are inserted in the holes 14. The holes 14 are formedso that their size in the up-down direction are larger than the lengthof the legs 18 c. Further, the pressing member 18 is biased towardupward by a spring 20. With respect to the pressing member 18, the legs18 c are restricted from moving upward at the upper edge of the holes 14and in the normal state, the upper end of the pressing member 18 is atthe same height as the upper end of the cylinder 13.

On the upper surface of the ceiling 18 b of the pressing member 18, tworidges (protrusions) 21 which extend in the diameter direction arerespectively formed at the positions that face each other in theleft-right direction having the axis of the spinning shaft 11therebetween.

2. Performance Changing Ring 30

In the embodiment, the performance changing ring 30 is constituted by aflywheel. The performance changing ring 30 has a plate shape. On thebottom face of the performance changing ring 30, an annular step 31 isformed which can house the flange 12 of the shaft unit 10 from the lowerside. Further, on the upper face of the performance changing ring 30,two protrusions 32 which protrude upward are respectively formed at thepositions that face each other in the right-left direction having theaxis of the spinning shaft 11 therebetween. On the lower parts of theprotrusions 32, recesses 33 are respectively formed which can house theprotrusions 15 of the shaft unit 10 from the lower side. Further, on theupper face of the performance changing ring 30, tongues 34 are formedwhich extend upward along the outer side of the respective protrusions32. The tongues 34 protrude higher than the protrusions 32.

Alternatively, the performance changing ring 30 may be constituted by amember that includes a protrusion on the outer peripheral face forfacilitating an attack on an opponent toy top 1 or a member thatincludes a recess on the outer peripheral face for averting an attackfrom the opponent toy top 1. Such a member may be provided instead of orintegrally with a flywheel.

3. Body 40

The body 40 has a disk shape. As illustrated in FIG. 2, the body 40includes a base 400 and a transparent cover 401 that has approximatelythe same shape as the base 400 in the plan view and is placed on thebase 400.

In the outer periphery of the body 40, an uneven pattern 40 a is formed.Further, at the center of the base 400, a round hole 41 is formed. Thetransparent cover 401 covers the part excluding the round hole 41 andthe after-mentioned arc slits 46. In the bottom face of the body 40, acircular recess 42 is formed which can house the protrusions 32 of theperformance changing ring 30 from the lower side.

The circular recess 42 is defined by an inner peripheral wall 43 a, andtwo hooks (first hooks) 44 which protrude inward in the radialdirections are respectively disposed on the lower end of the innerperipheral face of the inner peripheral wall 43 a at the positions thatface each other in the front-rear direction having the axis of thespinning shaft 11 therebetween.

Further, at the center section in the up-down direction on the innersurface of the inner peripheral wall 43 a, two protrusions 47 whichprotrude in the radial directions are respectively disposed at thepositions that face each other in the right-left direction having theaxis of the spinning shaft 11 therebetween.

Furthermore, on the lower end surface of the inner peripheral wall 43 a,two irregular units 45 which is formed by concaves and recessescontinuing in a line and which engage with the ridges 21 arerespectively disposed at the positions that face each other in theright-left direction having the axis of the spinning shaft 11therebetween.

Further, the circular recess 42 of the body 40 is also defined by aceiling wall 43 b, and arc slits 46 are formed in the roof wall 43 b,into which the tongues 34 of the performance changing ring 30 can beinserted from the lower side. The arc slits 46 have such a length thatallows the tongues 34 to move an adequate distance.

4. Identifying Member 60

FIG. 6 is a perspective view illustrating the identifying member 60. Theidentifying member 60 is attached to the round hole 41. The identifyingmember 60 is used for identifying the toy top 1 and the player.

Although it is not illustrated in the drawings, identifying members 60having different designs and/or colors from each other are provided foridentifying one another, and the one identifying member 60 selected by aplayer is attached to the round hole 41.

The identifying member 60 is formed in an approximately shortcylindrical shape as a whole. The upper surface center section of theidentifying member 60 is concaved to form a mortar shape, and decorationbumps 61 and operational recesses 62 are formed on the edge thatsurrounds the concave, two operational recesses 62 being respectivelyformed at the positions that face each other having the axis of thespinning shaft 11 therebetween. The flange 12 of the shaft unit 10 canbe inserted in the operational recesses 62, and the shaft unit 10 whichis inserted in the operational recesses 62 is moved so as to operate theidentifying member 60.

On the outer periphery of the identifying member 60, two grooves 63 inwhich the protrusions 47 enters when the identifying member 60 isinserted in the round hole 41 are respectively formed at the positionsthat face each other having the axis of the identifying member 60therebetween. Each groove 63 includes an introduction section 63 a whichextend in the axis direction of the identifying member 60, a guidesection 63 b having a part that inclines with respect to theintroduction section 63 a and connects with the introduction section 63a, and an engaging section 63 c which extends in the directionorthogonal to the axis of the identifying member 60. Among thesesections, the introduction section 63 a guides the identifying member 60to the first depth position in the round hole 41 when the identifyingmember 60 is inserted in the round hole 41. Further, the guide section63 b guides the identifying member 60 which is at the first depthposition to the second depth position that is not as deep as the firstdepth position by the protrusions 47 sliding along the groove walls withthe rotation. Furthermore, the engaging section 63 c prevents theidentifying member 60 from falling out from the round hole 41 due to thegroove walls and the protrusions 47 engaging with each other at thesecond depth position.

FIG. 8A to FIG. 8D illustrate the attachment configuration of theidentifying member 60. The attachment of the identifying member 60 iscarried out as described below.

First, in the state where the protrusions 47 are matched with theentrances of the introduction sections 63 a in the up-down direction(FIG. 8A), the identifying member 60 is inserted in the round hole 41from above (FIG. 8B). In such way, the identifying member 60 reaches thefirst depth position in the round hole 41. Next, the flange 12 of theshaft unit 10 is inserted in the operational recesses 62 and theidentifying member 60 is made to turn in a predetermined direction.Then, the protrusions 47 slide along the groove walls and enter theguide section 63 b from the introduction sections 63 a. First, theidentifying member 60 is made to turn at the same depth position. Then,when the identifying member 60 is further rotated, the protrusions 47slide along the inclined groove walls of the guide sections 63 b. Insuch way, the identifying member 60 gradually rises in the directionparting from the round hole 41. Thereafter, when the protrusions 47 passthe inclined groove walls, the identifying member 60 reaches the seconddepth position and the protrusions 47 are guided to the back of theengaging sections 63 c. The second depth position is not as deep as thefirst depth position. Then, the protrusions 47 engage with the groovewalls of the engaging sections 63 c.

Next, the shaft unit 10 is attached to the body 40. In the state wherethe shaft unit 10 is attached to the body 40, the upper section of thecylindrical pillar 16 is inside the round hole 41 and the upper surfaceof the cylindrical pillar 16 abuts the lower surface of the identifyingmember 60. In such way, the identifying member 60 is fixated to the body40.

Here, the identifying member 60 is detached from the body 40 in thereverse procedure of the above attachment procedure. In such case, theprotrusions 47 are pulled out from the grooves 63 following the reverseroute of the route described in the above attaching.

When the identifying member 60 is fixated to the body 40 as describedabove, the following advantages can be obtained.

That is, although the identifying member 60 once need to be moved in thedirection going deeper in the round hole 41 in order to detach theidentifying member 60 from the round hole 41, moving of the identifyingmember 60 can be prevented since the upper surface of the cylindricalpillar 16 abuts the lower surface of the identifying member 60. In suchcase, the cylindrical pillar 16 functions are a stopper. As a result,the identifying member 60 can be reliably prevented from falling outfrom the round hole 41.

On the other hand, the identifying member 60 cannot be attached in thestate where the body 40 and the shaft unit 10 are assembled. As aresult, the toy top 1 can be prevented from spinning in the state wherethe identifying member 60 is half way attached.

Assembling Method

Next, an example of the assembling method of the toy top 1 will bedescribed. Here, it is assumed that the shaft unit 10 is alreadyassembled. Further, it is also assumed that the identifying member 60 isattached to the round hole 41.

First, the shaft unit 10 is fitted in the performance changing ring 30from the lower side such that the protrusions 15 of the shaft unit 10mate with the recesses 33 of the performance changing ring 30.Subsequently, the assembly is brought toward the body 40 from the lowerside. In this step, the tongues 34 of the performance changing ring 30of the assembly are set to predetermined ends of the arc slits 46 of thebody 40 (FIG. 9A). In this state, the hooks 17 of the shaft unit 10 donot overlap the hooks 44 of the body 40 in the vertical direction. Thisstate is referred to as a coupling releasable state. Thereafter, theshaft unit 10 of the assembly is pushed toward the body 40. With this,first, the performance changing ring 30 is pressed to the lower face ofthe body 40. Further, the spring 20 shrinks and the hooks 17 of theshaft unit 10 are relatively pushed up higher than the hooks 44 of thebody 40. Subsequently, the shaft unit 10 together with the performancechanging ring 30 is turned with respect to the body 40 until the tongues34 reach the other ends of the predetermined ends (FIG. 9B). This turnis a relative turn of the assembly of the body 40 and the performancechanging ring 30 with respect to the shaft unit 10. FIG. 9B illustratesa state in which the shaft unit 10 has been already turned relative tothe body 40 and the performance changing ring 30. After this step, thehooks 17 of the shaft unit 10 are aligned with the hooks 44 of the body40 in the vertical direction. When the shaft unit 10 is released, thelower face of the hooks 17 of the shaft unit 10 abuts the upper face ofthe hooks 44 of the body 40 by the action of the biasing force of thespring 20.

The state where the lower surfaces of the hooks 17 of the shaft unit 10and the upper surfaces of the hooks 44 of the body 40 respectively abutis the coupled state. In such way, the shaft unit 10, the performancechanging ring 30 and the body 40 are coupled with one another. The toytop 1 is thus assembled.

How to Play

Next, an example of how to play the toy top 1 will be described.

In this example, a player spins a toy top 1 to battle with an opponenttoy top 1.

In such cases, a launcher 50 as illustrated in FIG. 10 is used to applya rotary force to the toy top 1. The launcher 50 includes a disk (notshown) therein. The launcher 50 is configured such that when a string(not shown) wound around the disk is pulled by means of a handle 51while a spiral spring biases the disk in a certain rotational direction,the disk is rotated, and a top holder 53 is rotated accordingly. Therotation of the top holder 53 is transmitted to the toy top 1 throughforks 54 that protrude downward, so that the toy top 1 is rotated. Here,the forks 54 are inserted in the arc slits 46 of the body 40. Then, whenthe handle 51 of the launcher 50 is completely pulled, the disk and thetop holder 53 stop rotating while the toy top 1 continues rotating bythe action of its inertial force. Accordingly, the toy top 1 moves awayfrom the top holder 53 along the tilted faces 54 a of the forks 54. InFIG. 5, the reference sign 52 denotes a rod that is retractable into thetop holder 53. When the toy top 1 is loaded in the top holder 53, therod 52 is pushed in the top holder 53 by the upper face of the toy top1. For example, the rod 52 is used for detecting attachment/detachmentof the toy top 1.

The toy top 1 thus launched is led to a predetermined field where itspins. When the toy top 1 collides with an opponent toy top 1, theimpact or friction of the collision produces a force that acts in thebody 40 in the direction opposite to the spinning direction of the shaftunit 10 and the performance changing ring 30, and the body 40 therebyrelatively turns in the direction opposite to the spinning direction ofthe shaft unit 10 and the performance changing ring 30.

Then, the ridges 21 of the shaft unit 10 engage with the irregular units45 of the body 40. Here, since the biasing force of the spring 20 actson the ridges 21, if the shaft unit 10 reaches the engagement releaseposition by the shaft unit 10 relatively turning with respect to thebody 40 and changing the engaging position every time the impact forceof the collision occurs, the hooks 44 of the body 40 are released fromthe hooks 17 of the shaft unit 10 so that the body 40 separates from theshaft unit 10 by the action of the biasing force of the spring 20.Accordingly, the toy top 1 is disassembled as illustrated in the rightpart of FIG. 1.

Variations of the Present Invention

While an embodiment of the present invention is described, the presentinvention is not limited to the embodiment, and various changes may bemade without departing from the spirit of the present invention.

For example, in the above embodiment, the protrusions 47 are formed onthe round hole 41 side and the grooves 63 are formed on the identifyingmember 60 side. However, as shown in FIG. 11, the grooves 63 can beformed on the round hole 41 side and the protrusions 47 can be formed onthe identifying member 60 side in the opposite manner.

Further, in the above embodiment, the upper surface of the cylindricalpillar 16 abuts the lower surface of the identifying member 60. However,the identifying member 60 can abut any part. It is sufficient as long asthe identifying member 60 can be supported at the engaging position.

Moreover, in the above embodiment, the case where the identifying member60 is attached to the body 40 as an example of a component is described.However, a performance changing member which changes the weight andshape in order to vary the characteristics of spinning and attacking canbe attached instead of the identifying member 60. Further, a decorationmember for the sole purpose of decoration can be attached instead of theidentifying member 60. Furthermore, although the identifying member 60is formed in a cylindrical shape in the above embodiment, theidentifying member 60 can be formed in any shape as long as it includesan insertion unit which can be inserted in the round hole 41.

Furthermore, a member having the same configuration as the identifyingmember 60 can be used as a fastener of the toy top 1. For example, theupper section of the fastener can be formed as a head section having alarge diameter and the lower section thereof can be formed as a shaftsection (insertion unit) having a small diameter and the grooves 63 areformed on the shaft section. Then, another component can be sandwichedbetween the head section and the member to which the fastener is to befixated so as to fixate the other component. In such case, it issufficient that a through hole in which the shaft section of thefastener can be inserted is formed in the other component. As for theother component, the transparent cover 401 which covers the base 400 canbe considered, for example. In the embodiment, the transparent cover 401is fixated to the base 400 in advance. However, the transparent cover401 can be attached by being sandwiched between the fastener and thebase 400. It is needless to say that a plurality of components can beattached in a state sandwiched therebetween.

Further, in the above embodiment, the protrusions 47 are formed on theinside of the round hole 41 and the grooves 63 are formed on the outsideof the identifying member 60. However, this can be in the oppositemanner.

Here, although the grooves 63 respectively include the introductionsections 63 a, the guide sections 63 b and the engaging sections 63 c inthe above embodiment, it is sufficient that the guide sections 63 b areformed as the grooves 63. The introduction sections 63 a are not neededif the identifying member 60 can be inserted to the first depthposition. Further, the engaging sections 63 c are not needed as long asthe identifying member 60 can be prevented from falling out by theabutting of the protrusions 47 to the wall surfaces of the guidesections 63 b after the identifying member 60 is guided to the seconddepth position by turning and the shaft unit 10 is attached. However,the engaging sections 63 c act as members to temporarily attach theidentifying member 60 and the shaft unit 10 can be attached in the statewhere the identifying member 60 is temporarily attached. Thus, the shaftunit 10 can be attached easily.

Further, wall surfaces which function as the guide sections 63 b andwall surfaces for preventing the identifying member 60 from falling outor turning in a reverse direction can be formed instead of the grooves63. Moreover, wall surfaces which function as the engaging sections 63 ccan be formed instead of or in addition to the wall surfaces forpreventing the identifying member 60 from falling out or turning in areverse direction.

Although various exemplary embodiments have been shown and described,the invention is not limited to the embodiments shown. Therefore, thescope of the invention is intended to be limited solely by the scope ofthe claims that follow and its equivalents.
